A pharmaceutically acceptable salt of (R)-3-(acetylamino)-3-methoxy-2-oxo-1-azetidinesulfonic acid can be prepared by culturing Chromobacterium violaceum A.T.C.C. No. 31532 at about 25.degree. C. under submerged aerobic conditions on an aqueous nutrient medium containing an assimilable carbohydrate and nitrogen source.
β-Lactams having a sulfonic acid substituent in the 1-position and one or two substituents as specified in the 4-position and an amine function in the 3-position and their use as antibiotics.
β-lactams having a sulfonic acid substituent in the 1-position and one or two substituents as specified in the 4-position and an amine function in the 3-position, are prepared by sulfonating a corresponding β-lactam having a hydrogen substituent in the 1-position and a protected amino substituent in the 1-position and removing said amino protecting group.
